Bill,
I seem to have gotten the Java Firefox Extension to work on Firefox 3:
http://simile.mit.edu/repository/java-firefox-extension/java-firefox-extension-2.0.0.xpi
Once it's installed and Firefox is restarted, the Error Console should say
FooComponent.initialize {
Greetings: Hello World!
} FooComponent.initialize
The string "Hello World!" comes from Java. Also you should be able to
invoke
Tools -> Java Firefox Extension: Do It!
and get an alert of 43. You should also be able to open a new window,
invoke that same menu command, and get 44. This shows that there is only
one instance of the Test class shared across windows.
The fix was to move the Java class instantiation code out of the XPCOM
code back into the chrome code. The chrome code
http://simile.mit.edu/repository/java-firefox-extension/firefox/chrome/content/scripts/browser-overlay.js
has to do more work now, which makes it a little less pretty, but it
works. On the other hand, we can do away entirely with all that policy
setting hack! Frankly, I don't know why I didn't use this method before! :-)
Let me know if you find any problem.
